Description

A gypsum board ceiling settlement joint treatment structure

technical field

The utility model relates to a suspended ceiling structure for indoor decoration, in particular to a settlement joint treatment structure for a suspended ceiling of a gypsum board.

Background technique

The gypsum board ceiling has a good decorative effect and is cheaper than other materials, so it has become the first choice for the majority of decorators to decorate the ceiling. --Surface treatment.

Generally speaking, the gypsum board will expand and deform with the change of ambient temperature and humidity during use, and the surface of the single-layer paper-faced gypsum board ceiling will be cracked and deformed after construction. Therefore, the construction process requires that if the unilateral distance of the ceiling exceeds 12 meters, expansion joints must be provided to ensure the flatness of the top surface. After the expansion joint is set, it is necessary to make corresponding treatment on the surface of the gap to avoid the impact of burr or unevenness on the appearance.

The above-mentioned treatment of the expansion joints, on the one hand, the construction is more cumbersome, and the construction period is delayed; on the other hand, the seams are easy to scatter the dust and dirt inside the ceiling. In addition, the gap is left during construction, and the gap will be large or small in the later stage, affecting the overall aesthetics.

Contents of the invention

The purpose of the utility model is to provide a gypsum board ceiling settlement joint treatment structure, which can simplify the construction process and improve the overall aesthetics and durability.

In order to achieve the above object, the technical solution adopted by the utility model is: a settlement joint treatment structure of a gypsum board ceiling, including a clamping strip and left and right edge trimming strips respectively located on both sides of the clamping strip, the width of the clamping strip is the same as The width of the seam of the gypsum board is matched, and the barbs are provided at the corresponding left and right edge strips, and one end of the left and right edge strips is provided with a bend that cooperates with the barbs. A snap connection is formed, and the other ends of the left and right edge trimming strips are respectively fixedly connected to the gypsum boards on the corresponding sides.

In the above technical solution, the clamping strip is composed of left and right sides and a middle bottom, the barbs are respectively arranged under the left side and the right side, and the middle bottom is provided with a deformation-tolerant bend. The deformation-tolerant bending is at an included angle of 170°-150°, and the clamping strip is made of PVC integrally formed structure.

In the above technical solution, the edge trimming strip is composed of the vertical edge provided with the bending and the connecting edge parallel to the gypsum board, which is L-shaped, and the connecting edge is fixed to the gypsum board by screws.

In the above technical solution, the gypsum board includes two layers of boards stacked up and down, and the two layers of boards are fixed by adhesives or screws.

In the above technical solution, the gypsum board is installed on the keel frame, and the keel frame is composed of several main keels and several sub keels, and the keel frame is provided with segment openings corresponding to the seams to form a unit Type keel frame, each unit type keel frame corresponds to a suspender fixed with the main structure.

Due to the use of the above-mentioned technical solutions, the present invention has the following advantages compared with the prior art:

1. In the utility model, the clamping strip is engaged with the left and right edge strips, and the width of the clamping strip is adapted to the width of the seam. The left and right edge strips are fixed to the gypsum board, so that the seam can be closed. On the one hand, it eliminates the need to deal with the rough edges and unevenness of the gypsum board on both sides of the seam, which reduces the difficulty of construction and ensures the consistency and smoothness of the seam treatment. On the other hand, the clip covers the seam to avoid dust and dirt in the ceiling scattered;

2. There is a deformation-tolerant bend on the bottom edge of the card strip, which provides expansion and contraction tolerance for the deformation of the gypsum boards on both sides, ensures the complete connectivity of the ceiling finish, and prolongs the service life of the ceiling;

3. Double-layer gypsum board is used to ensure the beauty and smoothness of the ceiling finish and prevent cracking;

4. The segmented dragon skeleton structure reduces the impact on the integrity of the ceiling finish when the gypsum board expands and settles, and reduces the amount of deformation.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment 1: Referring to Figures 1 and 2, a settlement joint treatment structure for a gypsum board ceiling includes a clamping strip 1 and left and right edge trimming strips 2 respectively located on both sides of the clamping strip 1. The width matches the width of the seam of the gypsum board 3, and it is advisable to fit tightly. The barb 4 cooperates with the bend 5, and the two cooperate to form a snap connection, and the other ends of the left and right edge strips 2 are respectively fixedly connected with the plasterboard 3 on the corresponding side.

The clamp strip 1 is composed of left and right sides and a middle bottom, the barbs 4 are respectively arranged under the left side and the right side, and the middle bottom is provided with a deformation-tolerant bending 6. The deformation-tolerant bending 6 is at an included angle of 155°, and the clip 1 is made of a PVC integrally formed structure. Through the included angle of the deformation-tolerant bending 6 and the elasticity of the PVC material itself, on the one hand, when the clamping strip 1 and the edge-receiving strip 2 are combined, it is convenient to clamp, and on the other hand, when the gypsum board 3 is stretched and deformed, it can absorb a certain amount of deformation , to reduce the impact on the ceiling finish.

The edge-receiving strip 2 is composed of a vertical edge provided with the bending 5 and a connecting edge parallel to the gypsum board 3, which is L-shaped, and the connecting edge is fixed to the gypsum board 3 by screws.

As shown in Figure 1, the gypsum board 3 includes two layers of upper and lower laminated boards, the two layers of boards are fixed by adhesives, and double-layer 9.5 mm thick paper-faced gypsum boards are used to ensure the ceiling finish Beautiful, smooth, prevent cracking. The gypsum board 3 is installed on the keel frame 7, and the keel frame 7 is constructed by several main keels and several sub-keels. Type keel frame, each unit type keel frame corresponds to a suspender 9 fixed with the main structure. The segmented keel frame 7 can reduce the impact on the integrity of the ceiling finish when the gypsum board 3 expands and settles.

During installation, the left and right trimming strips 2 are first engaged and connected with the clamping strips 1 respectively, and then embedded in the gaps between the gypsum boards 3, and the trimming strips 2 are fixed on the gypsum board 3 by self-tapping screws, and the gypsum boards 3 Apply putty on the surface and paint with white latex paint.
